Q: My father found this print being used as backing for an old photograph he inherited from his mother. The print is labeled “Execution of the Conspirators.” It consists of two panels. The left is labeled “Praparing (sic) for Execution” and the names of the conspirators, Surrat, Powell-Payne, Harold, and Atzerodt, are at the bottom. The right panel is titled “Springing of the Trap” and shows them hanging. We’ve been to Ford’s Theater, the Smithsonian, and Lincoln’s summer cottage at Soldiers Home, but we’ve never seen this particular picture in any of their collections. Anything you can tell us would be helpful.
